谁帮忙把我的毕业论文摘要翻译成英文

铜的导电性能好，具有较强的耐腐蚀性能，因此，铜或铜合金一直被视为同轴电缆内导体的首选材料。但铜的密度较高，铜资源比较稀少，且纯铜导体的价格较高。随着复合技术的不断发展与进步，在保证导电性能的前提下采用复合技术，用廉价的金属部分替代铜以降低生产成本，已经成为国内外研究开发人员努力的目标。其中铜包铝导电排是一种比较理想的替代品。
经过测算，铜包铝电力电缆与铜导体电缆性能相同条件下相比：可节约铜材78%，节约原材料成本20%以上，重量减轻40%。只要每吨铜价不低于4 000美元，铜包铝导体的电力电缆与相同的铜导体电力电缆在价格上的优势都在20%以上，铜价越高（铝价基本在2 500～2 700美元之间徘徊）价格优势越大。
国外工业发达国家自上世纪六、七十年代开始广泛使用包缚法生产铜包铝、铜包钢等双金属复合线材。美国、日本等国已形成规模巨大的产业，各自拥有具有一定特色的专利技术。在21世纪的今天，国内铜包铝材料生产设备和工艺已趋于成熟，而且2000年信息产业部也制订了行业标准。较早开发试制铜包铝导线生产线的大连、西安等几家企业也有了商机。
针对现有生产工艺技术中存在的不足之处，在生产工艺上，本文采用挤压铸造方法制作铜包铝坯料，最后采用热挤压工艺，这种生产工艺明显地提高产品的均匀性、厚度可塑性、结合可靠，具有生产率高，材料成本低、产品导电率高、电化学性能稳定等优点。然而，铜包铝母线槽排挤压技术的研究是真正意义上的以铝节铜，在节省铜资源的方面具有十分重要的意义。
这是我毕业论文的摘要，我也用过网上一些在线翻译的网站，可是感觉翻译得很差劲，希望大家能翻译得准确一点，我毕业就靠它了。非常感谢！谢谢大家的帮忙！

Answer 1

Conductive properties of copper, and has strong corrosion resistance, therefore, has been copper or copper alloy inner conductor coaxial cable is considered the material of choice. However, the higher the density of copper, copper scarce resources, and higher prices of copper conductors. With the continuous development of composite technology and progress and to ensure performance under the premise of conducting the use of composite technology, with low-cost alternative to copper metal parts to reduce production costs, has become a research and development efforts at home and abroad goals. conductivity copper which is an ideal scheduling alternatives.
After calculation, copper conductor power cable with copper cable performance compared to the same conditions: copper 78% savings, saving more than 20% of the cost of raw materials, 40 percent weight. As long as the price of copper per ton of not less than 4 000 U.S. dollars,包铝copper conductor power cable with the same copper conductor power cable advantages in terms of price in more than 20% higher copper (aluminum basic in 2 500 ~ 2 hovered between 700 U.S. dollars) greater price advantage.
Foreign industrial countries since the last century, the sixties and the seventies began to widely used on behalf of the production of copper tied packages, copper clad steel wire, such as bi-metallic compound. The United States, Japan and other countries have become large-scale industries, each with certain characteristics have a patented technology. Today in the 21st century, the domestic copper material production equipment and technology has been mature, but in 2000 the Ministry of Information Industry has also developed industry standards. Trial early development of copper wire production line Dalian, Xi'an and other business opportunities with several companies.
Current production technology for existing deficiencies in the production process, the squeeze casting method of this paper, the production of copper blank, and finally hot extrusion process, the production process is obviously to improve product uniformity, thickness plasticity, combined with reliable, high productivity, low-cost materials, products, high conductivity, electrochemical performance and stability advantages. However, the copper busbar row extrusion technology is a real sense of the section of copper to aluminum, copper-saving resources in the areas of great significance

Answer 2

The copper electric conductivity is good, has the strong anti-corrosive performance, therefore, the copper or the copper alloy have regarded as in the coaxial cable the conductor first choice material. But the copper density is high, the copper resources are quite scarce, and the pure copper conductor's price is high. Develops unceasingly along with the compound technology and progresses, uses the compound technology under the guarantee electric conductivity's premise, reduces the production cost with the inexpensive metal part substitution copper, already became the domestic and foreign research development personnel's goal diligently. And the copper alclad electric conduction platoon is one quite ideal substitute. after the reckoning, the copper alclad power cable and under the copper conductor electric cable performance same condition compares: May save the copper material 78%, saves raw material cost above 20%, weight saving 40%. So long as each ton copper number is not lower than 4 000 US dollars, the copper alclad conductor's power cable and the same copper conductor power cable's in price superiority above 20%, the copper number is higher (aluminum price to pace back and forth between 2 500~2 700 US dollars the price superiority to be bigger basically).
The overseas industrially advanced country started from the 1960s-70s widely to use Bao Fufa to produce the copper alclad, bimetal compound wire rods and so on copper Baotou Steel Factory. Countries and so on US, Japan have formed the scale huge industry, has respectively has certain characteristic patented technology. In the 21st century's today, the domestic copper coated aluminum material material production equipment and the craft already tend to be mature, moreover in 2000 the information industrial department has also drawn up the profession standard. Developed trial manufacturing copper coated aluminum conductor production line's Dalian, Xi'an and so on several enterprises also to have the opportunity early.
Deficiency which exists in view of the existing technique of production technology, in the technique of production, this article uses the extrution casting method manufacture copper alclad semifinished materials, finally uses the hot extrusion craft, this kind of technique of production enhances the product the uniformity, thickness plasticity, the union to be reliable obviously, has the productivity to be high, the material cost is low, the product conductivity is high, merits and so on electrochemistry stable property. However, the copper alclad bus bar rabbet pushes aside presses technical the research is in the true sense by the aluminum festival copper, is saving the copper resources the aspect to have the very vital significance.
